有没有linking顺序问题？我看到 usockets link 落后于 libuv，也许我们可以尝试交换顺序：先到 link usockets。
您正在使用静态 linkage，并且 usockets 取决于 libuv，因此交换序列将解决问题。
相关问题：
Why does the order in which libraries are linked sometimes cause errors in GCC?

有没有linking顺序问题？我看到 usockets link 落后于 libuv，也许我们可以尝试交换顺序：先到 link usockets。
您正在使用静态 linkage，并且 usockets 取决于 libuv，因此交换序列将解决问题。
